Emperor Yong Ping was also afraid that the Princess Consort of Huaiyang would be harmed by others.
Although on the surface, the murderer was undoubtedly the Prince of Huaiyang, killing people in the palace was like stepping on an ant. The palace's defense was like a sieve. He couldn't be sure that no one was taking advantage of the situation, or that the real culprit behind the scenes was someone else or a group of people conspiring.
In any case, Emperor Yong Ping had lost his hair now. No one could be trusted and everyone was suspicious.
Even those guards, when they were really needed, they did not know who was on their side and who was planted by others.
Although it was completely out of good intentions for Duo Fu to protect the Huaiyang Princess Consort, it was not the case in the ears of others. They even thought that the Emperor was venting his anger on the Huaiyang Princess Consort and imprisoning her.
